I have 2 working PATA drives in the system with the correct slave/master configuration installed onto ASUS P7P55D-E LX mobo. They were find until I loaded the mobo drivers from the original CD, then POOF, they vanished. They appear in the BIOS as ODD0 and ODD1 and no longer appears as windows load up. I am quite sure it is something in the BIOS but I have not been able to figure exactly what to change or how to flash the BIOS. I am a newbie at building systems.
Yeah! UNfortunately it did nothing, so I just reinstalled OS while disabling jmicron drivers, waited until OS was loaded trhen rebooted without the PATA's and rebooted one more time, ere-enabling the jmicron drivers and then they reappeared in the system, thanks for trying to help though.
